Background Racial disparities in migraine have been reported in the US. Migraine in African Americans (AA) is more frequent, more severe, more likely to become chronic and associated with more depression and lower quality of life compared to non-Hispanic Whites (NHW). It is possible that racial differences in prescribing practices contribute to these differences, but little is known about the quality of migraine prescribing patterns in the US or whether racial differences exist. Objective To determine if racial differences in quality of migraine medical prescription care exist...

Objective The aim of this project was to evaluate the prevalence and pattern of musculoskeletal dysfunctions in migraine patients using a rigorous methodological approach and validating an international consensus cluster of headache assessment tests. Methods A physiotherapist, blinded towards the diagnosis, examined 138 migraine patients (frequent episodic and chronic), recruited at a specialised headache clinic, and 73 age and gender matched healthy controls following a standardised protocol. Eleven tests, previously identified in an international consensus procedure, were used to evaluate cervical and thoracic musculoskeletal dysfunctions...

Post-thoracotomy pain syndrome (PTPS) is a traumatic neuropathy that can affect as many as 50% of patients undergoing thoracotomy. Patients are often refractory to conservative management and may require multiple analgesics for adequate pain control. Botulinum toxin, derived from Clostridium botulinum, has many uses in treating conditions involving spasticity, dystonia, chronic migraine, and a variety of pain disorders including neuropathies. Botulinum toxin type A injections may provide an alternative or adjunct to improve symptom management in patients with PTPS...

Functional connectivity (FC) has been used to investigate the pathophysiology of migraine. We aimed to identify atypical FC between the periaqueductal gray (PAG) and other brain areas in rats induced by repeated meningeal nociception. The rat model was established by infusing an inflammatory soup (IS) through supradural catheters in conscious rats. Quiescent and face-grooming behaviors were observed to assess nociceptive behavior. FC analysis seeded on the PAG was performed on rats 21 days after IS infusion...

Angle closure is usually associated with older patients, as it typically manifests in middle to later life, being associated with an age-related increased lens volume. However, angle closure can occur in any age group if there is an anatomical predisposition that promotes pupillary block or an anterior pulling of the iris. During an acute angle closure, patients generally experience ocular pain, headache, nausea, vomiting and conjunctival hyperaemia. These attacks can be misinterpreted as migraine, particularly if subacute or chronic and the demographic characteristics of the patient do not suggest a primary angle closure event...

Background Previous functional MRI studies have revealed that ongoing clinical pain in different chronic pain syndromes is directly correlated to the connectivity strength of the resting default mode network (DMN) with the insula. Here, we investigated seed-based resting state DMN-insula connectivity during acute migraine headaches. Methods Thirteen migraine without aura patients (MI) underwent 3 T MRI scans during the initial six hours of a spontaneous migraine attack, and were compared to a group of 19 healthy volunteers (HV)...

Although transcranial direct current stimulation (tDCS) represents a therapeutic option for the prophylaxis of chronic migraine, the target area for application of the electrical current to the cortex has not yet been well established. Here we sought to determine whether a treatment protocol involving 12 sessions of 2mA, 20min anodal stimulation of the left primary motor (M1) or dorsolateral prefrontal cortex (DLPFC) could offer clinical benefits in the management of pain from migraine. Thirteen participants were assessed before and after treatment, using the Headache Impact Test-6, Visual Analogue Scale and Medical Outcomes Study 36 - Item Short - Form Health Survey...

Background A subgroup of migraineurs experience an increase in attack frequency leading to chronic migraine. Methods We assessed in rats the roles of dose and repeat administration of systemic isosorbide dinitrate (ISDN), a nitric oxide donor, on the occurrence and development of cephalic/face and extracephalic/hindpaw mechanical allodynia as a surrogate of migraine pain, and the effect of acute systemic sumatriptan and olcegepant and chronic systemic propranolol on these behavioral changes. Results A single high (H-ISDN) but not low (L-ISDN) dose of ISDN induces a reversible cephalic and extracephalic mechanical allodynia...

Migraine headache is a disabling brain disorder that affects millions of women in the United States. Many migraine sufferers are undertreated. Both inadequate treatment and overuse of abortive migraine medication can contribute to progression from episodic to chronic migraine disorders. A significant number of migraine headaches or severity of episodic migraine headaches warrants treatment with prophylactic medications for prevention. This clinical update reviews the pathophysiology and diagnosis of migraine headaches in women, discusses the efficacy of abortive and chronic pharmacologic treatment, and examines strategies to prevent progression from episodic migraine to chronic migraine...

The cis benzopyran compound tonabersat (SB-220453) has previously been reported to inhibit connexin26 expression in the brain by attenuating the p38-mitogen-activated protein kinase pathway. We show here that tonabersat directly inhibits connexin43 hemichannel opening. Connexin43 hemichannels have been called "pathological pores" based upon their role in secondary lesion spread, edema, inflammation, and neuronal loss following central nervous system injuries, as well as in chronic inflammatory disease. Both connexin43 hemichannels and pannexin channels released adenosine triphosphate (ATP) during ischemia in an in vitro ischemia model, but only connexin43 hemichannels contributed to ATP release during reperfusion...
